Help with Reservoir / Pump mounting

How do you mount the pump top directly under the reservoir without using tubing to connect them? Do you need a special fitting, does the reservoir come with a fitting to attach it? I want the reservoir to rest on top of the pump, which will be sitting on the group, maybe with some velcro. Sort of like how he did it in this picture:

These are the same items he used as well as what I will be using, the difference is, I want to use the top port where he has an led for intake.:
